“…In the past century, a combination of drought and increased human water use for agriculture and energy extraction has lowered the groundwater supply of this region (Ashworth, Coker, & Tschirhart, 1997). Many species throughout this region are currently threatened by declining groundwater flows in springs (Konikow, 2013), including the Leon Springs pupfish, Cyprinodon bovinus Baird and Girard (Black et al, 2016), and invertebrate taxa such as a diving beetle, Ereboporus naturaconservatus Miller, Gibson and Alarie (Miller, Gibson, & Alarie, 2009), the Socorro isopod Thermosphaeroma thermophilum Richardson (Lang, Shuster, & Houtman, 2012), and several species of gammarid amphipods and hydrobiid springsnails (Brown et al, 2008;Lang et al, 2003). Cryptic invertebrate species are commonly present in desert springs (Brown et al, 2008;Murphy, Breed, Guzik, Cooper, & Austin, 2012), suggesting that the number of imperilled taxa is likely to be even higher than reported.…”

Desert springs are highly threatened ecosystems inhabited by a substantial number of endemic species. Macroinvertebrate communities of five springs in the northern Chihuahuan Desert of west Texas and south‐eastern New Mexico were sampled seasonally. Rather than focusing on individual taxa, this study examined the community structure of springs to identify patterns that are likely to reflect both local conditions and potential dispersal barriers. In total, 46 774 individuals representing 109 taxa were collected with high relative abundances of gastropods, amphipods, and oligochaetes. Spatial variation in community composition was greater than temporal variation. Although there were differences in the salinity content and concentrations of several major anions and cations among sites, these were not significant predictors of difference in community structure. Two springs sharing the same groundwater source contained similar macroinvertebrate communities and had similar physicochemical conditions. Results from this study suggest that springs in the northern Chihuahuan Desert contain unique communities and endemic species owing to historical processes such as isolation and dispersal limitation, rather than contemporary processes such as environmental filtering and species sorting. Springs located in the northern Chihuahuan Desert, like those located in other arid regions of the world, are valuable for their biodiversity because of their distinct invertebrate communities and high rates of endemism. Thus, they should be conserved individually to ensure the preservation of unique species and communities.

“…This region of the body has received much attention from biologists interested in stygobitic beetles (Miller et al 2013; Spangler 1986), and these sclerites are intricately involved in locomotion, particularly wedging (Evans 1977). The similarity in form of these sclerites may be evidence of recent common ancestry, but this may also be the result of convergence as modifications to the ventral thoracic sclerites and the loss of a streamlined body are commonly observed patterns in distantly related subterranean diving beetles (Miller et al 2009; Spangler 1986). …”

Stygoporus oregonensis Larson & LaBonte is a little-known subterranean diving beetle, which, until recently, had not been collected since the type series was taken from a shallow well in western Oregon, USA, in 1984. Here we report the discovery of additional specimens collected from a nearby well in the Willamette Valley. Sequence data from four mitochondrial genes, wingless, and histone III place Stygoporus Larson & LaBonte in the predominantly Mediterranean subtribe Siettitiina of the Hydroporini. Morphological support for these results is discussed, and details of the collecting circumstances of the new specimens are presented. We argue that the biogeographic patterns of Nearctic Siettitiina highlight the likelihood of additional undiscovered subterranean dytiscids in North America.

Etruscodytes nethunsn. gen., n. sp.: the first phreatic water beetle from Italy (Coleoptera: Dytiscidae: Hydroporinae)

Etruscodytes nethuns, new genus and species of subterranean water beetle, is described from Italy. This phreatic beetle was collected pumping water from a well in Tuscany (Central Italy). It is the third genus of stygobiontic dytiscid beetle from Europe and the first record of a stygobiontic water beetle in Italy. Etruscodytes belongs to the subfamily Hydroporinae as well as the related genus Siettitia Abeille de Perrin, 1904 from France. The new genus shares with Siettitia the lateral stria on the pronotum entire, but differs from it in very wide subsquare head, prosternal process in contact with the lobed anterior projection of metasternum, absence of fusion of the sterna 2 and 3, elytra not completely fused and several other peculiar features.
